Section III 

PROCESSOR SETUP 

All adjustments discussed here appear under 

Processor

 in 

the Main Menu. 

Metering 

Meters

  gives an  overall 

picture of audio pro-

cessing action.  The Web 

interface gives a 2-color 

display that additionally 

provides audio level and 

gain reduction annota-

tion.  The two examples 

here  reflect  the  same 

program,  but not quite 

at the same moment. 

Processing Presets 

The NOVIA 272 comes with ten factory-programmed pro-

cessing presets and ten empty registers where you can save 

your own, customized ones.  We recommend that you start 

with one of ‘ours’ and nurse it into ‘yours,’ something that 

sounds best for your programming and market de-

mographics. 
In this contrived exam-

ple,  ‘Bob,’  the station’s 

P.D., has developed his 

own  version  of  our  fac-

tory 

(F) Country

  preset, 

and has renamed it 

Country-2 (Bob’s)

.  All processing parame-

ters are saved in each preset, and presets are saved along 

with all other user settings when you download a Hardware 

Profile backup (see Page 30). 
Creating presets is easy.  After you have nursed-in just the 

right sound for your station, scroll to the top of the 

Presets

 

menu  to 

Save Preset

.  Push the knob and, as instructed, 

— 16 — 

Name Your Preset

.  Finish with a 

Save

.  You’ll find your new 

preset at the bottom of the list. 
To delete a custom preset, scroll to the bottom of the list 

and select 

Delete

.    Navigate  the  flashing  

X

  to  the  preset  to  

delete and push the knob.  Factory presets cannot be delet-

ed. 

Setting Input Levels 

Adjust  the  appropriate 

Input Level

  under 

Setup/Inputs

/

 

(whichever input: 

Analog

Digital

 or 

Stream

 applies). 

Setting the level of the program source involves matching 

the dynamics of the incoming program audio to those of the 

‘gain-riding,’  slow-AGC  function.    It’s  best  to  use  program  

audio for this rather than tones.  With moderately pro-

cessed off-air feeds and contemporary music releases, pro-

gram peaks should consistently reach 

–3dB

 on the front-

panel LED meters.  Heavily processed music may need to be 

backed-down so peaks don’t go above 

–6dB

.  Material with a 

wide dynamic range may occasionally reach 

0dB

.  For a de-

finitive measurement, go to 

Setup/Processor/Meters

 and check 

AGC

 meter action.  The aim is to keep this meter hovering 

right around 

0dB

 (center-scale) most of the time. 

AGC 

AGC is a slow, wideband ‘gain-riding’ function that presents 

subsequent processing stages with a uniform level based on 

both  the  peak  and  the  average  content  of  the  audio  pro-

gram.  AGC is ‘gated’ to prevent ‘gain runaway’ during silent 

periods. 
The front-panel 

AGC

 indicator lights when the gate is open.  

The 

AGC

 designation below the OLED and Web interface 

meters is at normal brightness under this condition.  The 

LED   goes  off  and  

AGC

 grays-out during pauses in the 

program. 
AGC is ‘windowed’ as well.  This means that when AGC gain 

drifts outside its ±5dB ‘sweet spot,’ accelerated ‘makeup 

gain’ brings it back inside more quickly. 
 AGC is enabled 

 

AGC

 by default, but may be turned off for 

classical or jazz music to preserve 

pianissimo

 passages.
